Noob question: How do I update after successfully installing macOS and OCLP?

Hi, I have a 2017 MacBook Pro with an i7 and 16 GB of RAM. I updated to Sequoia 15.3 a day before 15.4 was released, and now I want to upgrade to the new version.

Do I need to go through the entire process again from scratch—like using a USB flash drive, downloading macOS, installing it, etc.?

Or should I just update OCLP, download the update from Settings, and then apply the root patches?
